HOOP-DRIVER.

. Specification of Letters Patent. Patented h1g1, 28, 1911.

Application filed July 13, 1910. Serial No. 571,864.

To all whom it may concern:

Be it known that I, CHRISTOPHER WVIN- SKILL, a subject of the King ofGreat Britain, residing at Hillcrest P. 0., in the county of Vancouver,in the Province of British Columbia, Dominion of Canada, have inventedcertain new and useful Improvements in Hoop-Drivers, of which thefollowing is a specification.

My invention relates to improvements in hoop drivers, and particularlyof the type adapted for the driving of wire hoops, and the objects of myinvention are to provide a simple and effective tool for this purposewhich may be very quickly and readily ground to different curvatures,and which at the same time may be adaptable for use on barrels of atleast two different sizes.

Further objects are to protect the handle of the tool and to enable thetool to get a firm grip on the wire being driven so that it will not belikely to slip during use.

WVith these and other objects in view, the invention accordinglyconsists of the improved construction hereinafter described in detail inthe accompanying specification and drawings.

In the drawings: Figure 1 is a perspective view of the hoop driver inposition, showing a portion of the barrel and hoop being driven. Fig. 2is a side view of the hoop driver. Fig. 3 is a front view. Fig. 4 is aperspective View of the shoe on the end of the handle. Fig. 5 is a planview of the bottom of the shoe. Fig. 6 is a transverse sectional detailthrough the end of the driver.

In the drawings like characters of reference indicate correspondingparts in each figure.

Referring to the drawings, A represents the handle of the driver havingan upper portion 10 of suitable form to be conveniently grasped by thehand of the workman, and a lower enlarged portion 11 adapted to receiveand support a tapered shoe B,which shoe is adapted to fit over thebottom and sides of the lower portion of the driver, and

the bottom is adapted to contact with the hoop C being driven. Theopposite sides 12 and 13 of the shoe are ground to diiferent curvatures,to suit different sizes of barrels, whereby, the one side of the driverwill fit one size of barrel, and the opposite side will fit adifferently sized barrel.

In order to enable the side edges to be ground readily, without thenecessity of grinding away the entire surface, said sides are formedwith apertures 14 and 15 eX- tending over a greater part of their area,and leaving only the thickness of the bottom 16 to be ground.

The bottom of the driver is formed on the underside with a centraldividing ridge 17 between the sides 12 and 13, and the bottom surface isconcaved between this ridge and the outer edges, as shown in Fig. 6;these concaves being adapted to receive and take a firm grip on the wirehoop being driven.

It will thus be seen that I have devised a very simple and effectiveform of tool well adapted to perform the work required of it and whichmay be used with great rapidity and which is not likely to becomedisengaged from the work during use.

What I claim as my invention is:

1. A hoop driver comprising a handle,

and a shoe on the extremity of the same having apertures on each side,said apertures extending over the greater portion of said sides,whereby, the edge of the bottom of the shoe may be readily groundwithout grinding the surface of the sides.

2. A hoop driver comprising a handle, and a shoe on the extremity of thesame, said shoe being formed on its under surface with a central ridgeand being concaved between said ridge and the outer edges.

In witness whereof I have hereunto set my hand in the presence oftwowitnesses.

CHRISTOPHER WINSKILL.
